Problems With rescue

Gavin reports

According to my London Underground sources there are people trapped on the Piccadilly Line between Russell Square and King’s Cross. The problem facing emergency services is the depth, at that point the tunnel, is between 150 and 200 feet down. People who have visited London may know these stations for their very long escalators. The tunnels themselves are also quite narrow, which could mean the tunnels themselves may have been affected by the blast. The emergency services are moving extractors down to take out smoke in the tunnels. This particular line is extremely congested, and was so at the time of the explosion. Becase the line is so deep, the casualty figures will likely remain low for some time, but then dramatically rise. If two trains were involved it could mean as much as 1600 people on board, with uknown figures for people who managed to escape.
